Let final temperature be θ

You have not given values for specific heat capacities, but any text-book will give the figures as

Iron = 460 J/kgK

Water = 4187 J/KgK

Heat lost by horse shoe = heat gained by water (mC δt)

1.5 x 460 x (600 - θ) = 20 x 4187 x (θ - 25)

690 (600 - θ) = 83740 (θ - 25)

414000 - 690 θ = 83740 θ - 2093500

2507500 = 84430 θ

θ = 29.7 C

Final temperature of horse shoe and water is 29.7 C
